## FAQs
### Q: What is Burner 2?
A: Burner 2 is an American upper rocket stage used to move payloads between orbits or toward interplanetary trajectories. It is powered by a Star 37 engine and classified as a solid-propellant rocket.

### Q: What rocket stage came before Burner 2?
A: The Altair upper stage preceded Burner 2 in the Burner family of American solid-propellant upper stages.

### Q: What succeeded Burner 2?
A: Burner 2A succeeded Burner 2 as the next variant in the American upper rocket stage series.

## Why It Matters
Burner 2 represents a critical advancement in upper-stage rocketry, enabling more precise orbital transfers and interplanetary missions. As a solid-propellant space tug, it provided reliable propulsion for payloads requiring trajectory adjustments beyond initial launch. Its development contributed to the evolution of upper-stage technology, allowing spacecraft to reach their intended destinations with greater accuracy. The Burner series, including Burner 2, played a significant role in expanding the capabilities of American space launch systems during the late 20th century.

## Notable For
- Powered by the reliable Star 37 solid rocket engine
- Classified as both a space tug and solid-propellant rocket
- Part of the successful Burner family of upper stages
- Provided crucial orbital transfer capabilities for American space missions
- Served as the predecessor to the improved Burner 2A variant

## Body
### Technical Specifications
Burner 2 is powered by a Star 37 solid rocket engine, which provides reliable thrust for upper-stage operations. As a solid-propellant rocket, it offers advantages in storability and simplicity compared to liquid-fueled alternatives.

### Classification and Role
The stage is classified as a space tug, a spacecraft vehicle specifically designed to move payloads from a reference orbit to a target orbit or direct them to interplanetary trajectories. This classification highlights its role in orbital maneuvering and mission flexibility.

### Development History
Burner 2 follows the Altair upper stage in the Burner family lineage and was subsequently succeeded by Burner 2A. This progression demonstrates the iterative development of upper-stage technology within the American space program.

### International Presence
The stage has documentation in multiple languages (English, Bulgarian, and Indonesian), indicating its recognition in the international aerospace community. With a sitelink count of 3, it maintains a modest but notable presence in space-related knowledge bases.
